FIELD OF THE INVENTION

The present invention relates to a clip, clamp or other support (“clip”) insertable for use with pipes in plumbing applications, but which can have other uses such as with cables and in other electrical applications.

BACKGROUND TO THE INVENTION

Pipes used in plumbing applications come in a variety of types and have differing wall thicknesses depending on the manufacturer, the pressure rating, the material used, the requirements of the particular application and/or the industry involved. Common types of pipes used are, copper, polybutylene or polymers of butylene, pex pipe (white) such as cross-linked polyethylene, PVC (poly vinyl chloride), multi-layer composite aluminium, galvanised metals, stainless steels.

Pipe clips are manufactured for use on pipes of common sizes normally referred to by their approximate inside diameter. Because of the different materials used, wall thicknesses and different pressure ratings, the outside diameter of the pipes will vary depending on the product For example ½ inch pipe may have an outside diameter of 0.57 inches (1.45 cm) to 0.85 inches (2.16 cm). Pipe clips are usually made from a semi flexible plastic or a metal, and such materials allow very little flexibility. Plastic clips often only have one fixing hole, and when fitted only come into contact with two thirds of the pipe. See examples of FIGS. 1A to 1C.

A difficulty with such prior art clips is that the differing wall thickness of the different types of pipes requires the use of different sized clips. Current clips will only accommodate a minimal differential in outside diameter therefore manufacturers need to produce a range of clip sizes (which are commonly colour coded so as to differentiate them) for each common pipe size e.g. half inch.

It is critical that the correct size clip for a specific outside diameter of a pipe be used. If the correct clip is not used, does not fit correctly or does not apply enough pressure to the pipe to restrain its movement, this can lead to common problems with pipes such as “water hammer” (banging noises), creeping sounds of the pipe, excessive movement and pipe damage.

Also, if a clip is over flexed (stretched) it will not return to its usual form and will not be able to be re-used.

The installer should always select and install the correct size clip to keep the pipe in place. However, the installer will need to carry a wide range of clip sizes and types to ensure that the appropriate clip is on hand when needed. Aside from the variation in colour, it can be difficult to distinguish (visually or otherwise) between similar clip sizes. The confusion this causes is time consuming and can result in the wrong sized clip being installed.

It is another problem with existing clips on the market that such clips only have one fixing direction (usually also only one hole, but may have two) which gives them only one or two method(s)/option(s) of attachment to a support surface. This means that the usefulness of a particular clip, even if it is the right size for the pipe to be secured, depends on where it is to be mounted. The installer may, also or alternatively, need to use different or additional products to assist in mounting the clip, e.g. wedge products, and therefore will need to carry a further range of products to this end.

It is therefore an object of the present invention to provide such a support (“clip”) which will ensure appropriate support yet confer a leeway on size matching between pipes and the clips; or at least to provide the public with a useful choice.

It is a further or alternative object of the present invention to provide a support (“clip” or range of “clips”) that will reduce the number of different sizes and/or types of clip that an installer would need to carry in order to ensure that pipes ranging in diameter from approximately ¼ inch to 5 inch and made from different materials can be secured; or at least to provide the public with a useful choice.

It is a further or alternative object of the present invention to provide a support (“clip”) which can be attached or mounted to a support surface in a variety of orientations; or which will go at least some way towards providing the public with a useful choice.

Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.

Further aspects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The purpose of the invention is to adequately support a pipe and prevent it from moving irrespective of the wall thickness or outside diameter of a pipe which falls within the diameter range tolerance of the clip. The clip is suitable for pipes but could also be used in other applications, for example in securing cables or solid rod.

In smaller diameter pipes or cables e.g. those up to 50 mm the clip tolerance would typically need to be 2-3 mm while, with respect to larger diameter pipes e.g. those over 50 mm, the tolerance would typically need to be up to 5 mm. The range of pipe or cable diameters that would preferably be covered by the invention would be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 65 mm, 80 mm, 100 mm, 125 mm, 150 mm, 200 mm, 250 mm and 300 mm.

As shown in FIG. 2 the support as a clip has an longitudinally extensile or linking region 1 which substantially encircles the pipe to be secured, and first and second end regions 2 and 3, which when in the open position relative to one another (as shown in FIG. 3A) allow the pipe to be positioned within the extensile or linking region, but when in the closed position relative to one another (as shown in FIG. 3B), have the effect of bringing the extensile or linking region of the support as a clip into firm contact around the outer surface of the pipe.

Preferably one of the end regions 2 is larger than the other end region 3 and provides a contact surface or cradle 4 around part of the inner diameter of the clip.

The extensile or linking region 1 is preferably arc shaped. Preferably when in an un- or non-deformed or unextended state its curve follows a substantially circumferential path. However the linking region can be flexible and can be deformed or extended (i.e. is extensile) by movement of the end regions away from and/or toward each other to allow for opening and closing of the support (i.e. clip). In this manner, the support is longitudinally extensile

The extensile or linking region 1 may also be flexible and extendable in the circumferential direction (i.e. is longitudinally extensile), which enables it to be stretched or extended to fit around pipe types of the same generic size (e.g. ½ inch and ¾ inch), regardless of the wall thickness of the pipe. In a preferred embodiment the extension is achieved by a series of ribs 5 able to expand in a concertina type fashion in order to increase the inside diameter 6 of the clip. Although flexible, the ribs are strong enough to maintain an adequate contact force against the outside diameter of the pipe to restrict pipe movement.

The ribs may take the form of a series of sinusoidal curves, as shown in FIGS. 3A and 3B, or alternatively may take other forms such as saw-tooth or square-tooth. FIG. 3C shows an embodiment where in the ribs 5 are in an alternating triangular-toothed type concertina arrangement.

The contact surfaces 7 of the ribs may be substantially flattened in order to provide a bearing surface or inner surface of the support (or clip) which bear or butt or mate with the outer surface or perimeter of the pipe or member being supported. The non-flexible bearing portion 4 on the inside diameter of the clip need not be exactly round, but rather may have a slightly elongate curve to accommodate differences in the outer diameters of various pipes. Such a non-flexible bearing portion 4 can also contribute to the inner surface of the support (or clip) which can bear upon or butt or mate with or against the outer surface or perimeter of the pipe or member being supported. Preferably when the support (or clip) is in a closed condition, the support is able to provide substantial support around almost the entire outer circumference or perimeter of the pipe by way of contact on these bearing surfaces.

It is preferred that the clip be made of a lightweight and durable material which is able to accommodate some degree of flexion. Some examples of suitable materials are plastics, polypropylene, polyethylene, PVC (poly vinyl chloride), ABS (acrylonitrile-butadiene-styrene), nylon, acetal polymers, polycarbonates, thermoplastics, polyurethanes or a very ductile metal e.g. soft temper aluminium. The ability of the extensile region to expand and contract elastically, in combination with the cross-sectional thickness used and the choice of a suitable material, results in a pipe support (or clip) which cannot be over flexed and which will pull back into more or less its original shape after being opened up or stretched. This means that the clip will not be permanently deformed if it is accidentally over-stretched while the support is positioned on a pipe being installed, and that it is also unlikely to tear or break during this process. An additional benefit is that the same support (clip) can be re-used if necessary.

In order to secure the clip in a closed position, the two end regions of the clip 2 and 3 must be brought together, and may subsequently be inter-engaged to hold the clip closed around the pipe. There are a numbers of ways that the end regions could be inter-engaged, however a preferable way of achieving this is by way of a common fastener 8 to be passed through a passageway 9 in the first end region 2 and also through a passageway 10 in the second region 3 as shown in FIG. 4. The end regions may have flat joining faces 11 and 12 which are then brought to butt against each other as the clip is closed. It may be that the joining faces 11 and 12 do not completely abut, however they will at least tend toward abutment as the clip is tightened around the pipe.

The passageway 10 in the end region 3 may be a diverging channel as shown in cross-section in FIG. 4. To create an appropriately shaped channel the profile of the passageway as it opens to the joining face 12 should be circular, whilst the profile at the end of the passageway which opens to the upper face 13 of the end region 3 should be substantially oval. This enables the fastener 8 to correctly align into the circular passageway 9 in the end region 2 of the clip while the joining faces of the clip 11 and 12 are still at a distance to each other, i.e. the clip is in an open or semi-open position, and retains the fastener 8 in place as the clip is closed to its final position. The alignment of the passageways 9 and 10 in the open position can be seen from the top view of the clip shown in FIG. 5.

The embodiment of the clip having a diverging channel, as shown in FIG. 4 also has advantages in terms of ease of manufacture because the clip must be formed in its relaxed, and therefore open, state. The axis of the passageway needs to be substantially normal to the plane of the joining face, however it may also be necessary to create the passageways in-mould while the joining faces are at an angle relative to each other. A metal core, or cores, can be used to make the passageways 9 and 10. This core follows the shape of the passageways 9 and 10 as per FIGS. 6A, 6B and 6C of the drawings and allows the manufacture of the holes to be aligned where the joining faces are not parallel to each other.

In some embodiments of the invention the inter-engagement is secured by way of a thread engaging fastener 14 as shown in FIG. 7.

In one preferment said fastener is a self-tapping style screw. The passageway 9 in the end region 2 of the clip is a round hole or aperture with an interference fit, i.e. it is able to be “tapped” by the screw, while the passageway in the top half of the clip 10 is a non-interference or sliding fit.

However, as well as securing the clip in the closed position, the fastener can simultaneously serve to affix the clip to a support surface 15 as shown in FIG. 8. This will obviously be more successful if the design of the clip provides a significant flat base surface 16 on the end region 2. In this situation is not essential that the fastener 17 be thread engaging. For example, a simple nail could be driven through the passageways 9 and 10, and into the support surface 15 to affix the clip. Providing that the head of the nail is large enough, it will still act upon the top surface 13 of the first region 3 in order to close the clip around the pipe.

One or more additional fixing holes 18 for fixing to a support surface may be provided. Preferably such holes are in an orientation whereby their axes are parallel with the axis along which the pipe would be positioned. A preferable arrangement of three fixing holes is shown in FIG. 8, although it will not always be necessary to employ all three at once. These fixing holes 18 could also be used a fixing or fastening points for cables or ties.

Preferably the arrangement of the fixing holes will allow the clip to be affixed in a variety of ways as shown in FIG. 9; namely to suspend the pipe from an edge of the support surface as shown at 19, to stand the pipe off from the support surface as shown at 20, or to support a pipe passing through a bore hole made in the support surface as shown at 21. The ability to provide all of these mounting options makes the clip versatile and easy to install.

It can be seen that a fastener to bring the two end regions 2 and 3 into proximity with each other may not be necessary depending on how the clip is orientated in respect to the support surface. For example, it may be possible to use two fixing screws 22 and 23 to simultaneously fix the clip to the support surface and hold the clip closed around the pipe, as shown at 24 and 25.

The support (or clip) may be formed from two materials via, for example, injection moulding, with the linking region being made of a relatively softer material and the end regions being made of a relatively harder or stiffer material.

It will be appreciated the support of this invention is preferably formed or moulded as a unitary member. The support can be a single piece of moulded polymeric material.

The moulding or forming of the support as a unitary member can provide various advantages. For example, a single part can be held by a user, applied about the pipe or the like to be supported (often can be done single handed by the user), the support can be extended or deformed into its extended longitudinal configuration or arrangement enabling the support to surround the pipe or the like. Once the support is encircling of the pipe of the like, the support's inner surface is substantially in contact or abutting or mating with the pipe or the like's outer perimeter or surface. The user can then apply a fastener or other fixation to secure the support in position and onto a supporting surface.

Advantageously, the support of this invention enables for a variety of different diameter or circumference/perimeter pipes of the like to be gripped and supported by the support. The linking region is longitudinally extensile so effectively enable a longer length of the support and its inner surface to surround or encircle the pipe of the like.

Suitable materials include polymers of sufficient strength so as to be capable of adequately supporting and/or retaining a pipe or the like in a desired position once the support is affixed to a support surface. Suitable materials characteristics yet further include those materials providing the above strength behaviour, yet capable of enabling the longitudinal extensile linking region to extend and/or contract as desired. In this manner, a material having a shape “memory” can be useful.

The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
